IMPROVEMENT IN ENVELOPES.

TO ALL'WHOM IT MAY CONCERN:

Beit known that I, SIGMUND ULLMAN, of the city, county, end State of NewYork, have invented a new and improved Envelope; and I do hereby declarethat the following is n full, clear, and exact description tbereofQwhichwill enable-others skilled in the art to make and use the same,reference beinf:r hed to the accompenying drawings, forming a part oithis specification.

This invention relates to a. new end useful improvement in envelopes,endA has for its object the folding of the ends of an envelope in eucha. manner as to ciectually preclude the possibility of letters or money(bills) being. abstracted Without'lteoring or defacing the envelope.Letters and' money are at present frequently .abstracted from theordinary envelopes, by means of a bent wire and other instruments,Without injuring or defocing them in the least. and my invention, it isbelieved, will eileetuelly prevent this system of pilfering.

In the accompanying sheet of drawings- Figure 1 is n view of the rearside of an envelope cut according to my improvement, and having one endunfolded.

Figure 2, a view ofthe rear side of the seme, having both ends folded.

Similar letters of reference indicate corresponding parts.

A represents the'body or main portion'of the envelope, the edges of thesides of which are connected by-a. double fold, a. This double fold,however, is not new, and is the some as one shown in an enveloperecently patented by me. The ends of the envelope are out and foldedquite differently from any envelope novi made.

The inner or rear side of the end of the envelope is cut obliquely fromthe double fold a outward to the ends, as shown et b 5in fig. 1, and theouter or face side of the end is notched out in V-form, as shown at e inthe same ligure. l

The end ofthe envelope is then folded over et each side of its centre,as shown by the dotted lines d d, one side lapping over the other asuitable distance, and both folded sides are then folded over on' thebody or main portion oil-'the envelope, e indicating the crease of thefold.,

The folded Yend, if an eyelet be used as o. fastening, is thenperforated, as shown at f, iig. 1. If sealingwax, g, be used, as shownin tig. 2, no perforation of course is required.

By thus cutting and folding` the end 'of the envelope, it is impossibleto insert a. wire or any instrument whatever into the envelope, andabstract a. letter or banknotes, without tearing or defacing theenvelope.

Having thus described my invention, what I claim es new, and desire tosecure by Letters 'atcnt, is-

An envelope, having;r its ends cut and folded in the mannersubstantially as herein shown and described,

SIGMUND ULLMAN.
